硅化作用

主期重晶石矿化在断裂硅化作用之后，其后有韧&脆性剪切带构造的叠加改造。

The main stage barite mineralization was after fracture silication , later was superimposed with tenacity-brittle shear fracture .

狼山群第2岩组底部的石英岩是硅化作用的产物。

Quartzite at the bottom of the second formation of the Langshan Group is the result of silicification .

硅化作用主要在成矿早期，温度较高（200～300℃），砷、金主要在这一阶段析出。

With precipitation of As and Au , silicification took place at the early metallogenic stage at relatively high temperature ( 200 ~ 300 ℃), forming silicified rocks .

大部分的扭折条带遭受强烈的硅化作用，有时还具有矿化现象，并含黄铁矿和黄铜矿。黄铁矿很多，并且含钴，在硫化物块体中成稠密的斑块。

Most of them are highly silicified and sometimes mineralized with pyrite and chalcopyrite . Pyrite is more abundant and cobaltiferous and occurs in heavy patches in the sulfide mass .

通过微量元素、稀土元素及硅同位素分析，查明硅质具有深部来源的特征，并指出喷溢到浅水盆地底部的海底热水的硅化作用是其主要的形成机制。

From the sample analyzed for trace elements , REE and δ ~ ( 30 ) Si , it is concluded silica may be derived from deep source . We propose that main genetic mechanism of chert formation is silicification from submarine hydrothermal fluid into shallow water basin .

志留纪后古潜山储层主控因素为志留纪&泥盆纪，特别是泥盆纪期间的岩溶古地貌及二叠纪岩浆热液（硅化）改造作用；

The key controlling factors to EKR-1 are paleo-karst morphology from Silurian to Devonian especially in Devonian and silicification by magma heat liquids in Permian .
